I would answer but all my reference material is at home and I am away for the weekend. I know they'll bolt right on. I can't remember the compression volume differences. I believe the valves are the same sizes but I can't swear to it.

Yeah I know they will bolt up but Im not sure about how it affects the CR either. You might want to check out ls1tech.com I&#39;m sure there is a thread about it.

you will get a little better flow from the 6.0 heads but you will raise the compression ratio with the 5.3 heads. i think the 5.3 heads flow 190 cfm vs 210 on the 6.0 heads.

Sorry I couldnt find a whole lot about the 5.7 heads.
